Summary | 0008510: Waves V12 plugin interface mirrored | ||||
Description | When opening a V12 plugin of Waves in either AU or VST3 format, the interface is mirrored upside down. | ||||
Steps To Reproduce | Open Waves V12 plugin interface in Ardour. In any other host it is not mirrored. | ||||
Additional Information | I checked the resource bundles; there is a PNG.zip package in each of these plugins. I suspect a wrong interpretation of each PNG file, possibly due to PNG graphics library coordinate handling. At the risk of violating copyright and other licenses, I will not include any of the PNG, only screenshots (how it is on Ardour 6.5 Mac, how it is supposed to be). | ||||

However I have done an ImageMagick identify -verbose analysis on one PNG for further investigation. Text output is attached. WavesPNG_identify_verbose.txt (2,720 bytes)

It's not an Ardour, issue. The same happen in other hosts (Reaper, ProTools) also some windows systems are affected: https://forum.waves.com/t/plug-ins-gui-upside-down/2148/3 |
|
Hmmm... I didn't do my research thoroughly then. Case closed. |
|
Delving deeper, I got word back from Waves' Tech Support. Seams they render the V12 GUI by *only* using Apple's Metal frameworks. My question now is: how are graphics rendered by Metal calls handled by the Ardour viewports? I think Waves just set a precedent here, if other plugin developers decide to switch over to Metal, this could get messy... |
|
Issue has been closed automatically, by Trigger Close Plugin. Feel free to re-open with additional information if you think the issue is not resolved. |
|
Ardour doesn't care or is nonthewiser. In both cases (AU, VST3) the plugin provides Ardour with an "NSView". The plugin host is ignorant about the technology used to render that. |
|
It's caused by how waves uses macOS metal API. One solution to this is to compile Ardour on macOS 10.14 (or later) with the 10.14 SDK. It is still unknown how the SDK the host was compiled with can affect plugin rendering (and only waves being affected), but it evidently does. |
